Internal Abstractions

Internal abstractions are only created in patch editors. They are represented by red patch boxes . This section shows how to add an ** internal abstraction ** into a patch.

A red patch is autonomous :

• it is not attached to any external reference, conversely to a blue patch,

• it only “exists” inside the patch where it was created.
